Question

Вычислите объем который займут 132 кг оксида углерода 4.Вычислите число молекул газа и атомов каждого вида,содержащееся в этом объеме!

Answer 1

Молярная масса СО2:  М = 44 г/моль

Считаем количество молей:

n = m/M = 132/0,044 = 3000

Если при нормальных условиях 1 моль занимает объем 22,4 литра, то 3000 молей займут объем:

V = 3000*22,4 = 67200 л = 67,2 м^3

Число атомов углерода С равно числу молекул СО2 и равно:

N(C) = N(CO2) = 3000*N(Авогадро) = 3000*6*10^(23) = 1,8*10^(27)

Количество атомов кислорода соответственно вдвое больше:

N(O) = 3,6*10^(27)

Ответ: 67,2 m^3; N(C) = N(CO2) =  1,8*10^(27);  N(O) = 3,6*10^(27)

Answer 2

Calculation of Volume:

To calculate the volume occupied by 132 kg of carbon dioxide (CO2), we need to know the density of CO2. The density of CO2 at standard temperature and pressure (STP) is approximately 1.977 kg/m^3

Using the formula for volume (V) = mass (m) / density (ρ), we can calculate the volume as follows:

V = m / ρ V = 132 kg / 1.977 kg/m^3 V ≈ 66.77 m^3

Therefore, 132 kg of carbon dioxide will occupy approximately 66.77 cubic meters of volume.

Calculation of Number of Molecules and Atoms:

To calculate the number of molecules and atoms of each component in this volume, we need to use Avogadro's number (6.022 x 10^23) and the molecular formula of carbon dioxide (CO2).

The molecular formula of carbon dioxide (CO2) indicates that each molecule of CO2 contains 1 carbon atom (C) and 2 oxygen atoms (O). Therefore, we can calculate the number of molecules and atoms as follows:

Number of CO2 molecules = (mass of CO2 / molar mass of CO2) x Avogadro's number Number of CO2 molecules = (132 kg / 44.01 g/mol) x (6.022 x 10^23 molecules/mol) Number of CO2 molecules ≈ 2.01 x 10^26 molecules

Number of carbon atoms = Number of CO2 molecules x 1 Number of carbon atoms ≈ 2.01 x 10^26 atoms

Number of oxygen atoms = Number of CO2 molecules x 2 Number of oxygen atoms ≈ 4.02 x 10^26 atoms

Therefore, in the given volume of 66.77 cubic meters, there are approximately 2.01 x 10^26 molecules of carbon dioxide, 2.01 x 10^26 carbon atoms, and 4.02 x 10^26 oxygen atoms.

Please note that these calculations are approximate and assume ideal conditions.
